Generally , Cutting wheels with thickness 1.0/1.2/1.6/.2.0mm are suitable for fast and easy cutting. Cut-off wheel with 2.5mm thickness is used for cutting common material. Cutting disc with 3.2/3mm thickness have long life and high profile stability.

Grinding wheel manufactured by Aluminum Oxide material with the thickness 6.0mm have long life and high profile stability. Depressed CenterGrinding Disc manufactured by white Aluminum Oxide material have best sharpness and can be easy cutting and grinding.

2. Basic principle of Abrasive flap disc choice

Silicon CarbideFlap Disc

(ZA) Zirconia Oxide Flap Disc

1)Aluminum Oxide Flap Disc is mainly used for grinding and polishing carbon steel metal, wood, metal, iron, welding rods etc. This kind of flap disc is also calledMetal Polishing Flap Disc, just because it mainly used for common metal steel.

2)Zirconia Oxide Flap Disc is professionally used for grinding and polishing stainless steel, aluminium steel and construction steel, mild steel etc. This kind of flap disc is also called StainlessSteel Flap Disc, just because its professionally using area .

Our abrasive flap disc can be installed in the electric or pneumatic tools and automated polishing production line for all kinds of metal, stainless steel, wood, plastic, rubber, plane, inner and outer surface, irregular surface and large area of long workpiece rust, hair removal assassination, grinding and precision surface finishing, Manufacturing, maintenance and repair industry.

3: Basic principle of Abrasive Fiberglass Backing Plate choice
